Blank Screen after Moto logo on startup

My Droid 4 goes to a blank screen after the Motorola logo appears during startup. I've followed the steps from Verizon's online tech support and wiped the data and attempted to reboot. However, when I try to reboot it just goes back to the blank screen after the Moto logo, as though nothing has changed. What can I do?

Some background info:

I've been unable to power off the phone completely for a couple of weeks. Powering off the phone with the power button always resulted in an automatic restart.
I've had to restart the phone about once per day during the last couple of weeks.
Before tonight, this blank screen thing was happening on about 3/4 of restarts. I just used soft reset over and over again until the phone would power up properly. Again, this started about 2 weeks ago.
